from a laymans standpoint i think most would be happy just knowing what will
work safely in their gun. fortunitly my gun has a savage action so changing bolt heads due to scarring from blown primers is no big deal.
i highly advise the use of norma brass for this reason as opposed to winchester. realize the pressure is still there but the brass handles it better.
to me a sticky bolt is the gun telling me when its had enough. i allways start
my testing with wildcat cartridges by loading 1 each for each combination i
want to use. then increase in 1 grain increments till i come to the stop sign.
since i want max performance i work backwards from there with my load testing. im currently using 64 gr h1000 with a 140. the gun works very well and is accurate with that load. i havent tried it on 90 deg days however.
nor do i intend doing so as this is strictly a hunting gun.
as for the old powders like h870, the only thing good about them is that they were available when nothing else was.
 
I found LEE 6.5X.300 WSM Dies on ebay, they are full length size dies.
I am using the Micrometer Redding 6.5 bullet seater, with neck bushings to
neck size only.
We are getting 3250 out of 142 SMK and 140 Berger Hybrids with 63.5gr H1000.
3500 from 107's.
ALWAYS WORK UP SLOW!!!! WATCH FOR PRESSURE!
NORMA brass is our choice, FED match primers
I seat .010 off the LANS, you can get too much pressure seated too far in or off!
 
I am looking for some help on a 6.5wsm reamer would this be a good choice for the 140 Berger vld.

LRI reamer:
6.5/300 wsm, neck 0.298", throat angle 1*30, free bore length 0.14"
 
H-1000 is too fast to fill the case, yes you can get pressure but you will use the entire .270 WSM case with VV N-570, Retumbo and Magnum and get the same or more velocity with less repeat less pressure. Check Quickload if you don't believe me.
 
My reamer is .297. I have never felt the need to turn necks. I have Norma and Nosler labeled brass. I have used a few Winchester cases with similar results.

I have a Wilson neck size die and I use a .295 bushing. I have retired only a few cases, even with two nitrocarburized barrels but most are the result of overloads and loose primer pockets. Two split necks so far.

I also have a Lee Collet die (at one time a regular stock item, 6.5-300 WSM is the label) which sits. I use a Redding .270 WSM full length die bushing die to make cases into 6.5 size. I have a Wilson seating die that was made from my reamer. Make sure you get the 6.5 VLD die stems. Test your seating die stem by turning it upside down and placing a bullet in it. A VLD stem will support the bullet but in most dies the bullet will bottom out and be seated by pressure on the metplat.
 
I am using Winchester 270 wsm brass necked downed with lee 6.5 wsm dies. Using 60.5 grs h4831 sc . I'm getting around 3180 ft/sec using 140 gr Berger vld hunting bullets. Approx. .60 to .75 inch groups. I have a 26 inch benchmark bbl 1x8.5 3 groove bbl. I'm now putting working on a benchmark 1x8 twist 5 groove bbl. So far I've shot 7 deer out to 202 yds. 4 dropped in their tracks. The longest one has run is approx. 70 feet. All, except one was heart lung shots. One head shot. I love my 6.5 x284 but I really like 6.5 wsm.

65WSM,
I know this post is old but I'm in the process of building a 6.5 WSM. I downloaded this data before but what I don't see is what bullet is being used for these calculations. Can you enlighten me?
 
140 Berger Hunting VLD is the bullet here. I have an 8 twist. I wish I had data for VithaVuori N-565 and R-26 but my Quickload is not up to date. Reloader 26 is the best performing powder, especially in short barrels, I have found with 140 gr bullets. Velocity with temperature stability.
 
BoatTail,

Think we have crossed paths on the WSM threads recently. Think it is so cool the gentleman above me has the username 65WSM. We bow to you as you have my years on trigger with 6.5 WSM than us probably.

To second his point and you know we share everything, our factory loads of 6.5 WSM have RL26 in them. Run about 60500 pressure. Will get numbers later. We have tried Norma MRP and IMR 7828 SSC. The latter was not very accurate and MRP was greasy. We mostly test off of our TXH-F10. We always choose something that burns 98% of the powder or more for cycling reasons.

MRP in a bolt gun with 22" or longer barrel, would probably be great. For custom loads we will use R33 as a compressed load. We get about 80 more FPS by doing this and it is at the same pressure as the RL26. A little greasy because it burns around 95% of it but not as bad as MRP.

RL26 or RL33 in our shop. Will show some numbers this evening with charge weight.

VA SILENT ARSENAL,
I'm pleased to learn about you and your company. I didn't know anybody was out there making factory ammo for the 6.5 WSM. Since I'm in the process of doing specifications for my reamer can you tell me what the wall thickness is on your 6.5 loads? I was going to go with a 0. 299 neck diameter which would allow me to have a .004 clearance for .0155 neck thickness. If I decide to buy ammo from you I'd like to be able to shoot it in the rifle so would consider increasing the neck diameter if I need to. Since I have not seen any Factory ammo up until now I was just going to go with my number but let me know so I can interchange with what you have. I typically turn my necks but since this is a hunting rifle I also like to have the option to shoot Factory Mo if I can.
 
BoatTail,

Appreciate that. Thought our concepts were genius. One parent case, tons of bullet diameters, common platforms, compact, versatile, and suppressed. :)

.299 is on every one of our reamer drawings for 6.5 WSM. Think we tried 15 different reamers before 2 of them are our go toos. Not sure who you working with for a reamer but short freebores are the enemy! If you have to little freebore, the bolt will be sticky and or get some swipe. Hope you are above .180" on freebore. We are over .200."

The neck thickness is going to vary a bit because of the different brass and processes we use. Native 6.5 brass, 270 WSM brass or 300 WSM brass. When I came up with all this mess, I said I never wanted to turn a neck or anneal and we don't. Have 7 or 8 reloads out of some 458 WSM that have never been annealed. A few recent 6.5 WSM build in TXH-F10 shoot .5 MOA. Have never split a neck or case. We did have some primers fallout of some Hornady and you will see below. Don't use them.

My short term advice is to not worry about wall thickness as much. I have a couple to-dos for you in the shop later, will prep all the different types and let you know.

I also recommend getting Bertram brass over the Federal resized brass. Bertram is so much tougher and consistent. You said you reload. If you would like, you can get a die set from us, and do it yourself. We share all of the load data freely. Below is some of our brass recommendations.

All cases are trimmed to 2.090" Just like max trim for 300 WSM.

300 WSM brass goes through 7mm, 270, and then 6.5 WSM dies.

270 WSM brass just goes through the 6.5 die.

6.5 WSM, obvious.

In order of preference.

1. 6.5 WSM Bertram Brass
2. Federal 270 WSM Brass
3. Winchester 270 WSM Brass
4. Any of the brands above in 300 WSM.

Stay away from Hornady. It is junk brass in our opinion.

Watch our 338 WSM segment on Youtube. I go over ammo there. It can give you some general perspective of our ammo.

V/r,

Richie

I changed my freebore to .220 so I can load Hornady eld-x and Nosler accubond long range to near the maximum of my 3.110 Wyatt extended well magazine. Berger bullets will need to jump a bit if I use them. I have the all the components for the build except for the reamer. Now I need to close on that with PTG.
 
O wow. Surprised you went that far. Keep in mind additional freebore in some calibers are there simply for pressure reduction. This was our problem. Definitely sounds like you are on the right track. Are you gonna go with their bore rider option? Dave preaches a lot about it.

I measured about 10 pieces of various brass and most were .155" thickness. One was .16" with flickering of .1558".

VA Silent Arsenal 6.5 WSM 143gr ELD-X Production Load
Can be used in all barrels but mainly 20". Short LOA for use in TXH-F10
LOA 2.840", 62.2gr of RL26. Our pressure meter(probes in the barrel) shows 60100-60200 psi of pressure. Speed average of last 10 shots. 2905 FPS. Out of a 24" barrel in it is close to 3050 FPS. Burns it all any any barrel length.

Bolt Gun, Custom Load, 24" Barrel
LOA 2.915", 72.8gr of RL 33. 10 shots average was 3120 FPS. Burns 98.5% of it. We only do compress loads by hand. Ammo machines don't like do it, powder spills are a regular.

Using some of my figures, with your increased LOA it doesnt change much of anything for speed. Sure does look cool. We have never seated a bullet that far out. You will look at 2.840 and think, what the he** are these guys doing. Loading short is very accurate.
